võnkesagedus

Võnkesagedus, often translated as oscillation frequency or vibration frequency, refers to the number of complete cycles a periodically repeating event or system completes in a unit of time. It is typically measured in Hertz (Hz), where one Hertz represents one cycle per second. For example, a sound wave with a frequency of 440 Hz completes 440 cycles of its vibration every second. Similarly, in physics, the võnkesagedus of a pendulum describes how many times it swings back and forth in one second. This concept is fundamental in understanding wave phenomena, including sound waves, light waves, and mechanical vibrations. The inverse of võnkesagedus is the period, which is the time it takes for one complete cycle to occur. Higher võnkesagedus corresponds to a shorter period, and lower võnkesagedus corresponds to a longer period. In electrical circuits, võnkesagedus is crucial for describing alternating current (AC) signals. The term is also applicable in fields like biology and engineering to describe cyclical processes.
